Fairy tail is about a guild of mages. There are many guilds in the land of Fiore, but their guild is the strongest. The series follow Lucy, a celestial summoner, Natsu, a fire-dragon slayer, Erza, a Requip magic user, Gray, an Ice-mage, Wendy, a sky-dragon slayer and my favorite Gajeel, a Iron dragon slayer. These six often team up against strong opponents like when Natsu and Gajeel fought Sting and Rogue, and they are considered the strongest team.

However, even though they're the strongest TEAM, there are certain members of Fairy Tail than easily can solo all of them. Those are for example Laxus, the Thunder-dragon Slayer and an S-class mage, Gildarts, the Crush-magic user, and Makarov, the Guild master.

The villain in this show hasn't been announced yet, but I'm pretty sure it's either the dragon Acnologia or the Death-magic user AND dark wizard Zeref.
